First add them all together = $13,137.67. Then divide that by how many addens you have (in this case 5) and that gives you $2,627.53 :)

Compare solving equations with solving inequalities. How are the processes similar or different?

Answers

Answer:

Similarities

1. Adding or subtracting a number from both sides.

2. Multiplying or dividing both sides by a positive number.

3. Applying an increasing function to both sides.

4. Simplifying one or both sides.

Differences

1. Multiplying or dividing both sides by a negative number changes the direction of an inequality. So we cannot multiply or divide both sides by a variable unless we know that the variable is either always positive or always negative. This is not a concern when solving equalities.

2. When applying a decreasing function to both sides of an inequality, the direction of the inequality changes.

3. Swapping both sides of an inequality also changes the direction of an inequality. Again we don't have to worry about this with equalities.

Polynomials please someone help me !!!



(x4)2

Answers

remember
(x^n)^m=x^(mn)

(x^4)^2=x^(4*2)=x^8
I strongly believe you meant (x^4)^2 as you're referring to polynomials.


(x^4)^2

= (x^4)*(x^4)

= (x*x*x*x)*(x*x*x*x)

= x^8

On the other hand, if you meant (x^4)2, then the answer is 2x^4

Hope this helps! :3

Can i get some help with #6

Answers

4(x^2) + 2 - (242) ➡0
(2^2 x^2 + 2) - 242 ➡0
4 (x^2 - 60)
Now factor: x^2 -60
4 (x^2 - 60) ➡0
4 ➡0[solve]
x^2➡±60 [by the way]
X ➡ ±  √15 [⬅this might be your answer if you're working with square roots]
Just break it up
4x^2 needs to equal 240
So find what equals 240 when multiplied by 4
